Diabetic retinopathy is a complication of diabetes that affects the eyes. It is caused by damage to the blood vessels in the retina, the light-sensitive layer at the back of the eye.In its early stages, diabetic retinopathy may not cause any noticeable symptoms. As the condition progresses, however, it can lead to vision loss and blindness.
Diabetic retinopathy is classified into two main types: non-proliferative diabetic retinopathy (NPDR) and proliferative diabetic retinopathy (PDR).In NPDR, the blood vessels in the retina become weakened and may leak fluid or blood. This can cause swelling in the retina, known as diabetic macular edema, which can lead to vision loss.
In PDR, new blood vessels grow on the surface of the retina or in the vitreous, the gel-like substance that fills the eye. These new blood vessels are fragile and can bleed, leading to vision loss.Diabetic retinopathy can be prevented or managed with proper diabetic control, regular eye exams, and prompt treatment of any vision problems. In some cases, laser surgery or other treatments may be necessary to prevent vision loss.
